Engine Trouble: 7 Common Symptoms

Symptoms of engine trouble should always be brought to a mechanic's attention as soon as possible. This way, you can hopefully address the issue before it gets worse and becomes extremely expensive to fix. Here are seven signs of engine trouble.

Knocking Noise

Extremely low oil can lead to metal-on-metal contact that causes a knocking sound. It's also possible that a knocking noise will emerge if the air-fuel mixture is igniting on its own rather than by way of spark plugs, which is a problem that should soon be looked at by a mechanic.


An extremely low oil level can result in friction that consequently causes vibrations to emerge from the engine.

Check Engine Light Turns On

When the check engine light comes on, it's not necessarily an indication that your engine is nearing failure. But it's still wise to bring your vehicle to the shop for computerized diagnostics so that any emerging problem can be addressed before they get worse.

Power Loss

It's not cause for alarm if your older vehicle with high mileage has slowly lost a small amount of power over the years. But if your car has suddenly lost a substantial amount of power, then you could be dealing with a serious issue, such as worn-out pistons.

Engine Stalls while Idling

This often occurs due to a fuel delivery problem. Fuel delivery issues should always be promptly fixed so that you're not put in danger by your vehicle stalling out on a busy road.


Because overheating can cause serious engine trouble, such as a cracked block, you'll want to make sure that any cooling system issues are taken care of quickly.

Excessive/Discolored Exhaust Smoke

It's worth taking a good look at the exhaust smoke's color because it could give you a hint about the underlying problem. Blue-tinted smoke suggests an oil leak. White smoke is a sign that coolant is leaking. Black smoke is an indication that too much fuel is burning.
